1. A process for conversion of organic compounds, said process comprising contacting said organic compounds with a crystalline zeolite catalyst at a temperature of between about 250°

  • C. and about 750°

    C. and a pressure within the approximate range of 105 N/m2 to 107 N/m2, said zeolite being characterized by a silica to alumina mole ratio of at least 12 and a constraint index within the approximate range of 1 to 12, said zeolite having undergone prior modification by treatment with one or more compounds containing metal elements of Group IVB to deposit thereon at least 0.25 weight percent of such metal element.
